APPARATUS FOR TESTING ALCOHOL.

Application filed September 15, 1927.

This invention relates to the process and apparatus for testing alcohol for the purpose of ascertaining Whether the same has been denatured and has for its object the pro.- vision of a very simple process for making such test and apparatus for carrying out the same.

In the drawing Fig. 1 shows a cabinet in vertical section provided with pockets adapted to contain the separate elements for carrying out the process; Fig. 2 is a sectional view on line 22 of Fig. 1; Fig. 3 is a cross section of the still illustrated at the left of Fig. 1; Fig. 4 is a section on the line 4-4 of Fig. 3.

A cabinet 1, provided with suitable recesses and a cover, may be utilized to contam the apparatus for carrying out the steps of the process. The apparatus for carrying out the process consists of a still-of novel construction and simple manipulation. The still 2 consists of two like chambers 3 and 4 preferably made of glass and for this purpose glass vials shaped to the configuratlon shown in the drawings may be'readily used. The

vials 3 and 4 are connected together with a nipple 5, preferably a double tapered cork, the opposite ends of which are introduced into the corresponding mouths of the chambers 3 and 4. A central channel 6 is pro vided in the nipple 5 and a vent 7 is provided in the outer surface of that portion of the cork which is connected to the vial 4 to permit the escape of air from the chamber 4. By reason of the removable connection between the chambers 3 and 4 either may be readily removed for the introduction therein of the liquids and chemicals required to carry out the process.

The steps required to test the liquid are as follows: Five drops of the liquid to be tested, measured by dropper 8, are introduced into the chamber 3 and the chamber 3 is then aligned with the chamber 4 by. inserting the free end of the nipple 5 into the mouth of said chamber. The still is then preferably held in horizontal position and the chamber 3 is heated. The necessary degree of heat may be obtained by the use of a burning match, the flame of which is applied to the outside of said chamber. During the application of heat the still is supported by grasp- ScrialNo. 219,661.

ing the chamber 4 with a hand. The heat applied to the chamber 3volatilizes the more readily volatile liquids contained .therein It is preferred to use glass vials to consti tute chambers 3 and 4 of a length of about two inches and one-half inch in diameter so that a large surface will be exposed to the heating flame and also that the volatilized liquids will come in contact with a large surface so as to be readily condensed. The amount of the liquid in the heating chamber 3 is insignificant when compared with the volume of the chamber so that the liquids will volatilize in a few moments after a heating flame is applied to the walls of the chambers. As soon as the chamber 4 is warmed by the volatilized liquid entering therein,

heating of thechamber 3 is discontinued. The air inthe chamber 4 is permitted to es cape in the outer atmosphere through the vent 7. The chamber 4 is then withdrawn from its connection with the nipple 5 and v five drops of water are added to the condensation product in the chamber 4. Thereafter three drops of a solution containing 3% potassium permanganate, 15% of phos I phoric acid, and distilled water, indicated as contained in the vial 9, are introduced into the chamber 4 and the contents of the chamber 4 is allowed to stand for about three minutes. taining 18% sulphuric acid, 25% ferrous sulphate, and distilled water, and three drops of a solution containing 1/10 of 1% of basic fuchsin, 1% sodium sulphite, andv distilled water are introduced in the order named into the chamber 4 and the contents is allowed to stand for about ten minutes. The ferrous sulphate solution is indicated in the drawing as contained in vial 10 and the fuchsin solu- Four drops of a solution contion is indicated in the drawing as contained 1 the outer atmosphere.
